NoiseProof: dB Meter & Log

NoiseProof turns your phone into a noise evidence recorder — not just a decibel meter. ■ Real-time dB meter See current, min, average and peak sound levels with a live waveform. Calibrate to match a reference meter. ■ Threshold auto-recording Set a level (e.g. 60 dB). When noise stays above it, NoiseProof records automatically — and saves the 2 seconds before the noise too. It stops when things quiet down. ■ Timestamped log Every event is logged with date, time, peak dB and duration. Night-time events (10 PM–6 AM) are highlighted — exactly what matters for noise complaints. ■ Scheduled recording Set it to watch a specific time window, like overnight. ■ PDF report Export a clean report — total events, night-time count, peak level and a full table — to share with your building manager or neighbors. ■ 100% private Recordings never leave your device. No account, no upload, no cloud. Note: phone-mic readings are relative reference values; certified measurement is required for legal disputes.
